Become a sponsor to Peter Polidoro

I build robotics and automate experiments for scientists studying animal brains and behavior.

I open source all software and hardware that I create, including Arduino and other embedded libraries and printed circuit boards for interfacing with common sensors and actuators.

Sponsorship allows me to put time into design and support and ship open source hardware to sponsers.
